Secondary loop doesn't work

Hi I got a problem with my secondary loop in my template page.php.
I’m trying to display some testimonials, the code that retrieve those testimonials works perfectly fine in my index.php but I won’t retrieve any testimonial if I make the call from my template page here is my code:
slideshow.php

<div class="jumbotron bg-black">
      <div class="row">
        <div class="container experience">
          <hr>
          <h2><strong>EXPERIENCIA</strong></h2>
          <hr style="width:300px;">
          <div id="myCarousel2" style="height:250px;" class="carousel slide" data-ride="carousel">
            <!-- Indicators -->
            <ol class="carousel-indicators">
                <?php
                    $query = new WP_Query(array( 'post_type' => 'testimonial','p' => $id, 'order' => 'ASC', 'showposts' => '11'));
                    $i = 0;
                    if($query->have_posts()):
                    while($query->have_posts()) : $query->the_post();
                    if($i == 0) { ?>
                        <li data-target="#myCarousel2" data-slide-to="<?php echo $i;?>" class="active"></li>
               <?php
                    }else { ?>
                        <li data-target="#myCarousel2" data-slide-to="<?php echo $i;?>"></li>
               <?php
                    }
                    $i++;
                    endwhile;
                    else: ?>
                    <p><?php _e( 'Oh God Why?' ); ?></p>
                    <?php endif;
                ?>
            </ol>
              <!-- Wrapper for slides -->
            <div class="carousel-inner" >
              <?php
                $j = 0;
                if($query->have_posts()):
                while($query->have_posts()) : $query->the_post();
                if($use_excerpt){
                     $testimonial['content'] = get_the_excerpt();
                } else {
                     $testimonial['content'] = get_the_content();
                }

                if($j == 0) { ?>
                    <div class="item active" style="height:250px; width:800px;">
             <?php
                }else { ?>
                    <div class="item" style="height:250px; width:800px;">
             <?php
                } ?>
                <div class="carousel-caption" style="width:800px;">
                  <p> <?php echo $testimonial['content']; ?></p>
                </div>
            </div>
            <?php
                $j++;
                endwhile;
                endif;
                wp_reset_postdata();
            ?>
            </div>

          </div>

        </div>
      </div>
    </div>
</div>

And here is my code of my template page:

<?php
/*
Template Name: Nosotros
*/
        get_header();
?>
     <div class="jumbotron-2">
      <div class="row">
        <div class="banner">
          <img src="<?php bloginfo('template_url')?>/img/banner/empresa.jpg" class="img-responsive" alt="">
        </div>
      </div>
    </div>

    <div class="container">
      <div class="row">
          <div class="col-lg-12">
            <div class="row">
              <div class="icon-b"><img src="<?php bloginfo('template_url')?>/img/icon-b.png" class="img-responsive" alt=""></div>
               <h2 style="text-align:center;"><strong><?php the_title(); ?></strong></h2>
              <hr>
              <div class="col-lg-4 col-md-4 col-ms-4"><br><img src="<?php bloginfo('template_url')?>/img/empresa.jpg" class="img-circle"  alt="Empresa PERCHISA Perforaciones en Chihuahua SA de CV"></div>
              <div class="col-lg-8 col-md-8 col-ms-8">
                   <?php
                         if (have_posts()) : while (have_posts()) : the_post();
                            the_content();
                         endwhile; else: ?>
                        <h1>No se encontraron articulos</h1>
                   <?php
                        endif;
                        rewind_posts();
                  ?>
              </div>
            </div>
          </div>
      </div>
      <hr>
    </div>
<!-- EXPERIENCES  -->
    <?php include(TEMPLATEPATH. '/slideshow.php'); ?>
    <!-- END / EXPERIENCES -->
    <?php get_footer(); ?>

If I move the include before the main loop is executed it works, I will apreciate your help.
